Field-Ready Load Cell Tester: Fast Troubleshooting
In field monitoring, abnormalities in sensor output often cause headaches - is it a wiring problem, or has the component itself drifted? A handy tester can help you avoid many detours. Kingmach's load cell tester is specially designed for this kind of daily troubleshooting. It can directly read millivolt signals and excitation voltages when it is turned on without moving bulky calibration equipment. We have seen many engineering teams shut down for half a day due to a faulty sensor at a critical stage of the project. Later, they always had a small tester in their bag to confirm the problem within five minutes. This device is compatible with common types such as vibrating wire type and resistive strain gauge. The panel is simple and easy for new users to get started with. Because protection has been considered for field operations, minor splashes and bumps are less likely to cause malfunctions. If your project at hand has many types of sensors, you can also contact us to customize the lead interface.
Technical Detail
Kingmach's load cell tester was designed with a lot of on-site feedback in mind: Everyone hopes that it is small and light enough, that the operation is not too complicated, and that the battery can last a whole day. So we reduced the weight of the whole machine to about 400 grams. It can work with two AA batteries, and the display backlight can be seen clearly in tunnels or at night. The internal circuit has been optimized and the zero-point drift is controlled at the microvolt level. In actual comparison, the data consistency with the laboratory desktop instrument is quite good. In addition to basic handheld testing, it also has a practical function: transmitting real-time readings to the mobile APP via Bluetooth for easy recording and sharing. We have encountered customers who need to monitor multiple measurement points at the same time. Threshold alarms can be set on the APP so that you don’t have to stare at the screen all the time. The matching carrying case can organize the tester, connecting cables and spare batteries together, and they can be opened and used at the scene. Because Kingmach itself makes sensors and monitoring systems, the wiring definitions for various sensors are relatively clear; if you use a non-standard interface, we can customize the adapter cable according to your needs to avoid having to buy it back and solder the plug yourself. Products will undergo high and low temperature aging and vibration testing before leaving the factory to ensure that transportation and on-site environments will not affect accuracy. In terms of after-sales, as long as it is not damaged by human force, we provide online diagnosis for general minor problems. If repair is really needed, it can be quickly handled through the global distribution network.

Yes. The main interface will display the sensor's millivolt output and the current excitation voltage value at the same time. There is no need to manually switch the range. For occasions where calculations are required, the screen will also provide the ratio value (mV/V), saving you the need to press the calculator.
The standard configuration is a peeled alligator clip to facilitate temporary connection. But if you tell us the specific model and pin definition, we can customize a connecting cable with an aviation plug on one end and a standard banana head on the other end. Many users will save the wiring scheme of commonly used sensors with us, and just place an order directly when reordering.
It is recommended to calibrate once a year, or check at any time when you have doubts about the measurement results. You can send it back to us for free calibration (you need to pay for the round-trip freight). If you have a cooperative local metrology institute, you can also follow the simple calibration process in the manual to perform it yourself.
The current basic model is a single-channel design. However, we have an optional solution with a multi-channel switching box, which can poll 8 measuring points through external buttons. This requirement is more common in bridge static load tests. We have customized similar combinations for several testing units before.
The APP supports Android and iOS. You can manually record single point data or set the continuous recording interval. The record file is directly saved as CSV and can be sent to yourself through email or WeChat. When opened on the computer, it will be in table format, with time, mV value, and mV/V all listed.
